Abstract
We report our measurements of specific heat variations versus temperature in the
neighbourhood of ferro-paraelectric transitions. Two typical exemples have been chosen : T. G. S.
for second order transition and PbTiOs for first order transition. The occurrence of a thermal
hysteresis in the second case is used to evaluate the latent heat associated with the transition.
